“…A partir de esas y otras observaciones, se han realizado esfuerzos encaminados a medir las emisiones del gas Radón 222 Rn en todos los sitios posibles (Segovia et al, 1999;Omori et al, 2007;Richon et al, 2010) con el propósito de reducir el riesgo, principalmente en las poblaciones más vulnerables. Sin embargo, los resultados no han sido definitivos, con el paso del tiempo la teoría no ha sido comprobada, ya que los sismos se siguen presentando sin que se detecten las emisiones atípicas de gas en todos los casos (Richon et al, 2010).…”

“…De manera, que antes de considerar la variación de los gases como muestras para la identificación de precursores de terremotos, es necesario examinar su relación con perturbaciones ambientales como presión atmosférica, marea, temperatura ambiental, lluvia, presión barométrica, humedad del suelo o de la tierra, temperatura del viento, perturbaciones volcánicas (Segovia et al 1999), etc. lo que demuestra la necesidad de una medición simultánea de parámetros externos durante la monitorización de gases y la creación de redes de estaciones.…”

RESUMENEl artículo discute desde un punto multidisciplinario el estado actual de las predicciones sísmicas con sustento científico basados en precursores físicos, métodos estadísticos y los requisitos mínimos que deben considerarse para identificar métodos razonables; especialmente, los encaminados a la prevención sísmica. Sobre la cultura de la prevención se discuten cambios históricos relacionados con la población vulnerable y marginal, su progreso en relación al desarrollo científico, la evidencia antropológica sobre la eficacia de las predicciones y su influencia en la cultura de la prevención para enfrentar riesgos comunes, el sistema de alerta temprana de sismos y la influencia de las predicciones en las expectativas y decisiones de inversión Palabras clave: sismo; predicción; prevención; antropología; sistema de alerta; expectativas de inversión CHALLENGES AND UNCERTAINTIES IN THE PREDICTION AND PREVENTION OF SEISMIC RISK ABSTRACTThis paper discusses from a multidisciplinary view, the state of the art of seismic predictions related to science-based studies based on physical precursors, methods based on statistical patterns and the minimum requirements to be considered in order to identify reasonable methods; especially, those aimed at prevention of seismic disaster. Culture of prevention, historical changes related to vulnerable and marginal populations, progress in relation to scientific development, anthropological evidence on the effectiveness of the predictions and their influence on the culture prevention to face common risks, seismic alert system and decisions and investment expectations derived from the predictions are discussed.

“…A number of authors [1][2][3][4][5][6][7][8] make this kind of predictions on the basis of soil-gas information, mainly the radioactive radon gas ( 222 Rn) data. Thus, an enhanced seismic activity responsible for changes in the convective velocity may account for anomalous temporal variations of the radon concentration and that of other gas species in the subsurface soil air [7][8][9].…”

Abstract. The present research is aimed at accessing the relationship between variation in the soil gases radon ( 222 Rn) and helium ( 4 He) and recently developed fissures and other neotectonic features in Nurpur and Nadha areas of the NW Himalayas, India. Two soil-gas surveys were conducted on/near known faults to reconfirm their position using soil gas technique and to check their present activity. During these surveys, soil-gas samples were collected along traverses crossing the observed structures. The data analysis reveals that the concentrations of radon and helium along the Dehar lineament and the longitudinal profile (Profile D) are very high compared to any other thrust/lineament of the Nurpur area. The Nadha area shows high values of radon and helium concentrations along/near the Himalayan Frontal Fault (HFF) as compared to the adjoining areas. This indicates the presence of some buried fault/fault zone running parallel to the HFF, not exposed to the surface and not delineated by satellite data but is geochemically active and might be tectonically active too. Hence, soil helium and radon gas patterns have been combined with morphological and geological observations to supply useful constraints for deformation of tectonic environments.
